4 Claims.

This invention relates to roof sumps, the object being to provide a newand improved form of sump comprising a body having a peripheral flangeto which the roofing is secured and having a series of comparativelylarge apertures above the same anda removable basket having aperturedside walls adapted to separate .foreign matter from the water owing intothe sump. and supported in spaced relation with the side walls of thebody to permit the material of larger sizes to pass directly to theoutlet at the bottom of the body, the basket being unattached to thebody to permit removal therefrom and ready replacement thereof.

These and other objects and novel features of the invention arehereinafter more fully described and claimed and shown in the preferredform in the accompanying drawing in which- Fig. 1 is a plan view of asump.

Fig. 2 is an elevation, partly in section, showing the features ofconstruction.

Heretofore roof drains or sumps have been made with a body and a hollowmember having apertures in the side walls having open end downward andusually bolted or otherwise secured in place and not subject to readyremoval.

In my improved form of roof sump I provide a hollow body I, the lowerend (preferably the bottom) of which is provided with a threadedaperture to receive the threaded end of a Waste conduit 2. The upper end3 of the body is open and is provided with a series of comparativelylarge apertures 4 extending in peripherally spaced relation thereaboutand above the flange 5 which receives the roofing 6. A ring plate l issecured on the upper side of the roofing element to seal the roofing tothe sump body as is the usual practice. Within the body of the sumpadjacent the upper end are a number of peripherally spaced lugs 8 andthe basket `9 has an outer peripheral flange lil supported by gravity onthe lugs 8 of the body. This arrangement of lugs and flange avoidsnecessity of providing a fastening means requiring detachments to permitremoval of the basket or manipulation of such parts in placing thebasket in the body. The upper end of the basket 9 is open and extendsabove the upper open end 3 of the body and the bottom I I of the basketterminates above the bottom of the body and inlet end of the conduit 2.Preferably the basket has a series of vertical slots I2-I2 thereinextending from near the upper open end to a point above the bottom II ofthe basket and the basket is provided below the lower end of the slotswith a series of apertures I3-I3 l and the bottom. wall II has similarapertures. The upper edge of the body may also be formed of notches I4opening throughV the upper edge.

The roof may be formedofwood, as indicated at 20 in Fig. 2, or may be ofconcrete and in any form of roof structure the flange 5 of the bodyfunctions to receive the roof covering. Itis also pointed out that theoutlet conduit may extend from the side of the body rather than from thebottom by the provision of a hub 2| on the side thereof to receive alateral conduit 'Z2-both shownby dotted lines in Fig. 2.

With the device installed in the roof as stated any foreign material ofcomparatively large size, less than that of the apertures 4, may passdirectly into the body and through the periphery elongated apertures I5in the flange I0 of the basket and thence pass directly to the outlet 2.The lighter material such as straw, dirt, brous material and the liketending to float on the surface of the water flowing to the sump, maypass directly into the basket through the slots or into the upper endwhich permits papers and other oating material of large size to enterthe basket. This prevents clogging of the sump. With this arrangementmaterial larger than the size of the apertures I3 will accumulate andwhen the basket becomes clogged it may be readily removed, the materialdumped therefrom and the basket repositioned in the body withoutnecessity of fastening or unfastening of parts for securing the same inplace.

It will be observed from the foregoing that the structure is ofextremely simple form comprising two separable parts functioning ashereinbefore described and is thus of less expense in manufacture and inerection in place as it is only required to position the flange on theroof in position to receive the roofing and the securing of the outletconduit thereto. Upon positioning the basket within the body theinstallation is completed.

It is to be understood that the invention is not restricted to specificforms of the parts as here shown and that various changes may be madewithout departing from the spirit and scope of the invention as setforth in the appended claims.

Having thus fully described my invention, its utility and mode ofoperation, what I claimvand desire to secure by Letters Patent of theUnited States is:

1. A roof sump comprising a hollow body having an open upper end adaptedfor attachment at its lower end to a Waste conduit, an external flangebelow the upper end of the body for securing the same to a roof and toreceive the roof covering, the'end of the body above the ange havingopenings, a basket having a bottom, an open upper end, and a peripheral.apertured flange therebelow, the basket being of less diameter than theinner diameter of the body and having apertures in its wall above thebasket flange through which waste material may flow with the water andsmall apertures below the flange for separating the waste material fromthe Water therefrom, and lugs projecting interiorly of the body on whichthe peripheral flange of the basket is supported.

2. A roof sump comprising a hollow body having an .open upper end andadapted for attachthe body for securing the saine to a roof and to with,a basket within the body having a bottom, an open end extending to abovethe upper end `'oi thebody,v and a peripheral flange therebelow, Ythebasketbeingrsupported in spaced relation with thebody by the flange, thesaid basket having a series of vertical slots in the upper portion ofthe wall .thereof and-,a series of comparativelysmall apertures .inthe'wall thereof below the slots and inthe bottorn,-saidyapertures'providing a means for retaining debris within the basket' andpermitting flow of water. therefrom, and means within the body-providinga support for Vthe basketv flange Aand permitting the free removal ofthe basket.

` 3. A roof sump comprising outer and inner sep- :receive a roofcovering in sealed relation therearable parts of cylindrical form, brothsaid parts' having open upper ends, the outer part having a peripheralange below its top for the support olV the same on a roof and adapted toreceive a roof covering in sealed relation therewith, the bottom of saidouter part having an opening to receive a waste conduit, said inner parthaving the open upper end thereof extending a distance above the openupper rend of the body, and the side walls and bottom of said inner parthaving apertures, lugs extending inwardly of the body below its top,and. means on the exterior of the basket by which it is supported on thelugs by gravity and 1 freely removable from within the body.

4. A roof sump comprising inner and outer separable parts of hollowcylindrical form, both the parts having open upper ends, the outer parthaving a peripheral ange below its top for support of the same on a roofand adapted to receive a roof covering in sealed relation therewith, the
